You (Steve) are called in to see your tutor to discuss your declining grades. To your delight you catch her with her high heels up on the desk, and turns out those mature wrinkly soles are sweaty and sore from being all day on her feet. She has you sniff and lick the insoles of those shoes, before licking and sucking her feet clean. Your tutor notices your throbbing erection and realises this is why you can't concentrate in class - plus you keep sneaking off to jerk off in the bathroom! After giving you jerking off instructions and a countdown to cum all over her soles, she decides you should wank over her feet every week so you'll not be distracted from your studies... You leave her office with the taste of your own cum in your mouth.
